An hour later, Hu bugui and others came back sweating. In order to collect the best spirit mines that song Tianxuan needed, they searched almost all the resource pavilions of the whole dizang sect.

They even ventured to dig several pieces of ten thousand year old black ice in a spirit mountain hundreds of miles away, although they didn't know what it had to do with alchemy.

Looking at all kinds of spirit mines piled up, song Tianxuan showed a satisfied smile on his face.

After pointing out the defects of the alchemy furnace, he began to command the people to melt the spirit mine to build various components, and then replaced the old components in the alchemy furnace one by one.

In this process, Hu bugui soon found the circle of lines on the cauldron. He really didn't know that it was the soul lines. He also beat around the Bush, hoping song Tianxuan could give some advice.

Naturally, song Tianxuan would not reveal his secret. He just found an excuse and prevaricated.

With his experience and insight, it's not too easy to find a reasonable and convincing reason. It's just that Hu, the master of medicine, has no ability to identify the true and the false, and even keeps nodding to show that he has been taught.

Until dark, almost 80% of the components of the alchemy furnace were replaced.

Because of the different materials, the appearance has also changed from pure yellow to colorful. Although it looks a little nondescript, it is in the eyes of Hu bugui who knows how to do it.

This brand-new alchemy furnace is much better than the one I've been guarding all my life.

"Ha ha ha, nephew Song Xian is really a talent!" After wiping the sweat on his forehead, Hu bugui gave song Tianxuan a thumbs up again.

With this brand-new alchemy furnace, his success rate of refining pills in the future will certainly be doubled. Maybe he will produce many top-quality pills. At the thought of that wonderful situation, his face will be happy.

Song Tianxuan just smiles and looks up at the starry sky above his head. He yawns: "Oh, let's call it a day. Let's all go back to conserve our energy and start the official alchemy tomorrow. By the way, elder Hu, have you prepared all the herbs I mentioned before? "

Referring to his professional field, Hu bugui immediately came to the spirit. He took out a list and said with pride: "three plants of Eulaliopsis binata, five fruits of longwenguo, ten leaves of guixinye... These ten herbs are all top-quality medicinal materials. In a hurry, he can only prepare so many. As for other top-quality medicinal materials, such as feiyansha and tianyugen, we have prepared at least five times the amount, which will definitely be enough at that time! "

Song Tianxuan nodded again and again. He said with satisfaction, "well, I've worked hard for you. I hope you can succeed at that time."

After that, he turned to leave. Hu bugui, who stayed in the same place, was already stunned. He murmured: "the legendary mysterious elixir, he wants to succeed once. Even if he is instructed by an expert, it's too mysterious. Is song Tianxuan really the genius of genius? "

After a whole night's cultivation, song Tianxuan's aura had been restored the next day. He came to Hu bugui's house with a clear mind.

Hu bugui and others also look ruddy and excellent. It seems that they took some pills last night to recover their aura.

Now that everyone is fully prepared, song Tianxuan doesn't say anything. With his order, the people who are already ready immediately start to take action.

According to the proportion needed for refining xuanlingdan, all kinds of medicinal materials were quickly evenly placed around the alchemy furnace.

Song Tianxuan checked and confirmed that there was no problem. Then he ordered someone to add charcoal to the furnace. Finally, he came to Hu bugui: "elder Hu, my accomplishments are limited. I'll give you the task of igniting the fire!"

Hu bugui immediately straightened his back, and a sense of divinity surged in his heart. He nodded hard, and then turned the aura.

After taking a deep breath, he clapped his hand at the furnace, and a pure fire went straight down. Shunjiang ignited all the charcoal.

"Keep the heat up!" Song Tianxuan reminded that he began to look at the soul patterns around the cauldron. With the increase of temperature, those soul patterns began to flash a light red light.

When the red light to a certain extent, song Tianxuan decisively opened the cauldron, and the rest of the people who had long been ready immediately threw all kinds of herbs in their hands at the same time.

The whole process was completed in a blink of an eye, and the cauldron was sealed by song Tianxuan again.

Boom boom!

The fire in the furnace became more and more intense. After two hours, the soul lines around the alchemy furnace were almost red. At this time, the alchemy furnace was once again filled with all kinds of medicinal materials.

Calculating the time is almost, song Tianxuan again beat the cauldron, people are no longer nervous, quickly put the second batch of herbs into it.

Bang!

Song Tianxuan pushed forward, and the cauldron was sealed tightly again. Hu didn't return to the cauldron, and he shot out several flames to further increase the temperature of the furnace.

For a whole day, people were constantly repeating this process, that is, Hu bugui's cultivation was deep, he was specialized in fire attribute aura, and he would take a few pills to persist for such a long time.

Song Tianxuan was only responsible for continuous observation and command, although he didn't have to do it himself, which was also very serious.

Fortunately, he had refined the mysterious elixir for countless times in his previous life. He was already familiar with it and could support it.

As for those apprentices who Hu did not return, they were the most relaxed. They just needed to see the right time to put all kinds of herbs into the cauldron.

"Stop!" After five times of adding medicinal materials to the cauldron, it was already dark. At this time, the cauldron began to emit strange fragrance. It was refreshing and energetic. When the fragrance reached a certain level, song Tianxuan immediately stopped drinking.

Hoo Hoo! Hu bugui clapped several palms, and the fire was more fierce, but he directly killed all the charcoal in the furnace. He took a long breath, and regardless of the ashes on his face, rushed to song Tianxuan and asked anxiously, "how is it, is it successful?"

Song Tianxuan shook his head and said, "not yet. Now the medicinal materials in the cauldron have just melted into liquid medicine. Although the liquid medicine has been mixed into one, the properties have not been completely integrated. Tomorrow is the key!"

Hu did not return to think for a moment, not from secretly nodding, he asked again: "well, what do you need me to do?"

Song Tianxuan frowned and said, "no, the last step can only be done by me. It's easy to be distracted when there are too many people. You can go outside and wait at ease!"

Although Hu bugui was unwilling, he could only leave the house with his apprentices, and closed the door gently with his eyes.
